14. Utility Key
Press this key to access the Utility menu, which
lets you configure the oscilloscope’s I/O settings, printer
configuration, file explorer, service menu, and other options.
15. Trigger Controls
These controls determine how the
oscilloscope triggers to capture data. See “Choosing Auto trigger
mode or Normal trigger mode” on page 78 and Chapter 4 ,
“Triggering the Oscilloscope,” starting on page 125.
16. Run Controls
Press Run/Stop to make the oscilloscope begin
looking for a trigger. The Run/Stop key will illuminate in green.
If the trigger mode is set to “Normal,” the display will not
update until a trigger is found. If the trigger mode is set to
“Auto,” the oscilloscope looks for a trigger, and if none is found,
it will automatically trigger, and the display will immediately
show the input signals. In this case, the background of the
Auto
indicator at the top of the display will flash, indicating that the
oscilloscope is forcing triggers.
Press Run/Stop again to stop acquiring data. The key will
illuminate in red. Now you can pan across and zoom-in on the
acquired data.
Press Single to make a single acquisition of data. The key will
illuminate in yellow until the oscilloscope triggers. See
“To start
and stop an acquisition” on page 75.
17. Waveform Keys
The Acquire key lets you set the
oscilloscope to acquire in Normal, Peak Detect, Averaging, or
High Resolution modes (see
“Acquisition Modes” on page 259),
and lets you turn Realtime sampling off or on (see page 263 ).
The Display key lets you access the menu where you can select
infinite persistence (see
page 255 ), switch vectors on or off (see
page 256 ), and adjust the display grid (graticule) intensity (see
page 256 ).
18. Horizontal Delay Control
When the oscilloscope is running,
this control lets you set the acquisition window relative to the
trigger point. When the oscilloscope is stopped, you can turn
this knob to pan through the data horizontally. This lets you see
